we have
![y=-x^2-6x+16](https://tex.z-dn.net/?f=y%3D-x%5E2-6x%2B16)
using a graph tool
see the attached figure
<u>The vertex of the quadratic equation is the point
</u>
That means that the maximum height of an arch is equal to ![25\ units](https://tex.z-dn.net/?f=25%5C%20units)
<u>The zeroes of the function are the points
</u>
That means that the width of the arch at its base is equal to difference between the zeroes
![=(2-(-8))=2+8=10\ units](https://tex.z-dn.net/?f=%3D%282-%28-8%29%29%3D2%2B8%3D10%5C%20units)
therefore
<u>the answer is </u>
The width of the arch at its base is equal to the difference between the zeroes

<h3>Answer :</h3>
ASA (Angle Side Angle) method can be used to prove ∆ABC ≅ ∆DEF
<h3>Solution :</h3>
In ∆ABC and ∆DEF
∠A ≅ ∠D (given)
AB ≅ DE (given)
∠B ≅ ∠E (given)
So, by ASA congruency criteria
∆ABC ≅ ∆DEF

Answer: 4xyz+5xy+3yz-9
Step-by-step explanation:
(SIGNAL RULES)
+(+) = +
+(-) = -
-(+) = -
-(-) = +
5xyz+xy+3yz-4-(xyz-4xy+5) -> 5xyz+xy+3yz-4-xyz+4xy-5 = 5xyz-xyz+xy+4xy+3yz-4-5 = <u>4xyz+5xy+3yz-9</u>
